BF said he was going to do a food shop 3 hours ago (10 minutes drive away). I started to get worried as to where he was so I called about 20 minutes ago and he said he was just at the shops, when I asked where he had been he said he decided to go for a drive for 2.5 hours. I thought this is a bit odd? I had no idea where he was and was genuinely a bit worried. AIBU to be a bit miffed or should I let it go?
